Abstract
The invention discloses a biomass hybrid fuel ignition system for a coal-fired power plant, which relates to a production ignition system using diesel oil as fuel to preheat a hearth. The biomass hybrid fuel ignition system enables environment pollution to be reduced, economic cost to be reduced and potential safety hazards to be eliminated. The biomass hybrid fuel ignition system is characterized by being provided with a blower 1, a feeder 8 and an igniter 20. When the biomass hybrid fuel ignition system is operated, powdery biomass can be mixed with fuel to be contained in the closed feeder 8 and can also be evenly, stably and continuously mixed with pressure air to form mist which enters the hearth of the igniter 20, and the mist is quickly ignited by high-temperature gas in the hearth prior to being timely mixed with secondary and tertiary high-temperature intake air to support combustion and is timely burned out without black smoke. The biomass hybrid fuel ignition system is low in plant straw economic cost, and capable of burning out the fuel without the thick and black smoke while generating high-temperature flame. Compared with use of the diesel oil, the use of the biomass for the system reduces environment pollution, lowers economic cost, and eliminates potential safety hazards. The biomass hybrid fuel ignition system is simple in structure.
Description
Technical field
The invention belongs to the operation production system of chemical mechanical equipment.Relating to a kind of coal-burning power plant uses diesel oil to be the bad igniting production system that needs igniting combustion supporting to use of fuel preheating burner hearth, underrun and/or ature of coal.
At present; Coal-fired plant boiler restarts, all will light a fire after new stove starts and shuts down maintenance, and traditional ignition method is to make fuel with diesel oil, with oil gun with the diesel injection atomizing and in the burner hearth internal combustion; Make temperature rising in its burner hearth, simultaneously coal is lighted; When the bad hidden danger of stopping burning possibly of underrun or ature of coal appears in boiler, want igniting combustion supporting at any time; Original power portion stipulates that new unit consumption oil index ceiling is 9000 tons; Blowing out restart point fire consumption oil limit is 3000 tons; Its igniting funds are no small spendings to power plant, therefore, and the major issue that the financial cost that reduction is lighted a fire with diesel oil has just become industry extremely to pay close attention to.Once developed a kind of " small oil gun " igniter in the eighties in last century, its consumption oil index and financial cost decline to a great extent, but new furnace igniting still need consume diesel oil about in the of 500 tons, and about diesel oil ton valency 8000 circles, the financial cost of its igniting is still than higher at present.And,, the dark smoke of incomplete combustion is still directly arranged to atmosphere for reducing the infringement of dark smoke to dust arrester on the flue.At present; Also have a kind of technology of directly coal dust in the boiler furnace being lighted, but this technology can only be useful for " good coal ", when boiler needs when combustion-supporting because of the ature of coal difference with plasma-arc; Just can not bring into play being used for, need rely on the combustion-supporting means of oil gun to carry out production run again.Plasma-arc is that Kufil, general continuous use will be changed once in 2 hours with the technology that coal dust in the burner hearth is lighted because of its " electrode " material directly; Because of it is changed frequently, cost of use is also very high; So traditional diesel oil that uses is the igniting production system of the fuel preheating burner hearth part that also comes with some shortcomings; Its weak point is: (1) when igniting the dark smoke that not exclusively produces of diesel combustion directly row to atmosphere, its severe contamination environment; (2) make fuel ignition and heating furnace with diesel oil, its financial cost still is higher; (3) make auxiliary equipment such as fuel requirement oil storage tank, oil pipe with diesel oil, have potential safety hazard near its body of heater.
